Hi Caleb,

I imagine your project ZX809 is starting to take shape, yes?  Did that Snocross chassis turn out to be in great shape internally as well as cosmetically?

The 121" and 136" versions of the Expert X offer 11" of true vertical travel, as measured at the lower swingarm pivot point, NOT at the rear idlers.  This point corresponds to the point directly below the rider on a 121" sled, so this is where you really "feel" the travel working for you.

The weight of the Expert X is ~60lbs, but keep in mind that we designed the X to be very beefy.  Those CNC-machined rails are 3/8" thick 6061-T6 aluminum and the swingarms are each made of two 1/4" thick 6061-T6 aluminum arms.  It could be lighter, but we prefer to stress durability in our designs.

I should have the motor monday night. I may go get the chassis next week but probably the week after, the kid doesn't care when I come to get it. What does the stock mxz-x race rear skid weight in relation to the xpertx?

That's hard to say since the ZX's final components are often hard to follow.  Over a standard SC-10 II/III, the Expert X saves about 10 pounds over stock, but add in the extra bracketry and reinforcement in the ZX version (have you seen those closed-in rear scissors?) subtract a few sets of wheels and I'd say the X saves around 13 pounds.

I'm anxious to see what kind of shape your chassis is in. What do you plan to do with the stock 440?  Is it fixable?

The stock 440 was toast and sold for $275 on ebay also. A belt got wet water skipping,slipped behind clutch and blew the seals out of the motor. It has been dunked a few times. I'm not concerned with it's shape as I'm going to replace every single bearing,bushing,steering end,etc. I'm going through it from top to bottom. The whole rear skid may just get replaced with and X though. Other wise I'll replace everything to replace there also.It'll be like a brand new machine. Parts are not to much and I'll do the labor. Why do you guys use KYB shocks instead of Ohlins/Ryde FX? I know KYB's are all right but a pain to tune and rebuild all the time.
